Desk• Service Level Agreements• Enhancement Request

Service Level Agreements

Two Way AgreementsBetween

Service ProviderAnd

Service Receiver-Czegel, 1999

Service Level Agreements

Help Desk might have SLA betweenBetween

Help Desk (Service Provider)And

Group of Customers (Service Receiver)

-Czegel, 1999

SLA

• Agreements typically specify–What services the provider provides–What targets it must meet

• SLA also specifies–Responsibilities of ‘receivers’ using

the services

SLA

• What is SLA ?• Why do we need to define Service

Levels ?• What SLA can we make about

Support Service?

SLA

• How should we define these Service Levels?• How do we use these defined

Service Levels ?• Should we exclude certain events

from our service level monitoring?

Why define Service Level?

• A Written Commitment or Agreement between two parties–The provider–The receiver (recipient)

Why define Service Level?

• Is SLA Legally Binding ?• Possibly, between two legal

entities (two separate companies)• Between departments of same

organization (IT and Service)

Why define Service Level?

• SLA is used to:Measure performance

Of Service Provider

In the Delivery of That Service

SLA and Support Plan

• Assignment asks for Support Plan• Broadly similar to idea of SLA

SLA and Support Plan

• Support Plan should define–What the service provider will

provide–The targets you plan to meet–Customer responsibilities

Targets are defined in Service Levels

SL Targets/Measures

• Targets to measure Help Desk Performance–How well the intended service is

being delivered–Success of Support Plan

SL for Support Service

Different Category of

Support Issue

SL for Support Service

EVERYTHINGCOVERED ?

Coverage

• In reality, things are more complicated• May need to define special

exception–Cope with issues outside our immediate

control

Possible Problems

• A call has been logged• Unable to contact user for further

information• Meanwhile target resolution time

passes• Who is responsible?

Possible Problems

• Perhaps put the call ‘on hold’–Unable to act without further

information

Possible Problems

• A call has been logged• A bug in third party software

is responsible for cause• Third party company is taking

time to supply the fix• Meanwhile target resolution time

passed

Possible Problems

• Put call ‘on hold’ while waiting for response• Keep users informed of progress

Summary – SLA

• Priority (identify category)

• Setting targets (response/resolution)

• Customer responsibilities• Exclusions• Monitor performance
